The polynomial function f(x) = 3x5 – 2x2 + 7x models the motion of a roller coaster. The roots of the function represent when th
cupoosta [38]

Answer:

x=0

Step-by-step explanation:

We have been given that a polynomial function f(x)=3x^{5}-2x^{2}+7x models the motion of a roller coaster. Every root of the polynomial represent when the roller coaster is at the ground level.

In order to find all the potential values of x when roller coaster is at the ground level, we find the zeroes of the polynomial by factoring it as shown below:

f(x)=3x^{5}-2x^{2}+7x\\f(x)=x(3x^{4}-2x+7)\\

The zeroes of this polynomial occur when either x=0 or 3x^{4}-2x+7=0.

The equation 3x^{4}-2x+7=0 have no real solutions. Therefore, the only time when the roller coaster is at the ground is at x=0

erma4kov [3.2K]
<span>3/5 of 215

Whenever you see the word "of" in a word problem, automatically think "multiplication".
3/5 </span>× 215
0.6 × 215
129

So, 3/5 of 215 is 129.
